My invention relates to loading devices "such as are commonly employed for deliver: 111g material to concrete mixers; andlt has for its objectto improve the-construction 6f the loader being open.

a the same, and adapt them forthe various uses to which loaders of this kind are put; In the accompanying drawingsFigure 1 is a side elevationof the invention as applied to a concrete mixer, the outer end of Fig-2 is a top plan view of the loader detached. Fig. 3 is a side elevation of the loader detached,'its

In such drawings, 2 designates the revolving drum of a concrete mixing machine, it

being formed with an axial feed opening 3. 4 designates the loader, which is represented 1 as being plvotally connected, at 5, with a it framework 6 surrounding the drum. The

loader is provided with a pivoted bail 7 the 1 f cross-bar of which carries a sheave 8 around which passes the cable 9by means of which the movements of the loader are controlled.

I The parts thus far described in their gen eral features and relationship are well known in the art and may be widelyvaried without departing from the essential features of my invention.

The loader 4 is formed with an openspout 10 through which the materials placed therer in are delivered into the drum, through the Tfeed opening 3, the delivery being effected by tilting the loader. It is of such shape and so proportioned to the other parts of the apparatus that when its lowermost position, as represented in Fig. 1,,it rests upon the groundxor other surface on which the mixer is supported. The oute'rend of the loader, that is, the one distant from the spout 10, is preferably shaped to have a flat bottom 11, so as to afford a broad support- 5% ing base, while the loader is being filled. [This portion of the loader is closed byan end wall 12 which is pivotally connected, as by hinges 15, with the'front or outer edge of the bottom 11.

bottom ll an'd against the end edges of such position ,to'closethe end of the loader, the wall then being vertically disposed; Se- "c'ured to the end 'wall at its ends are segmental shaped side pieces 14 whichjare adapted to lie just inside of the side walls 13, when the gate or end piece 12 is turned up to close I the loader, and which, practically form extensionsiof the said sidewalls when the end wall is let down to open the loader, is indicated in full lines in Fig. 1. I pro-j loader is being filled, for instance from wheel T ably perpendicular to the plane of the, flat alls the end wallIor gate 12"rests when'in i vide means for holding the'end wall in posi-' barrows that are beingmoved over the sur face on which the mixer and the loader rest, the endwall may be let down as indicated in full lines in Fig. 1, permitting the barrows to be wheeled directly into the loader and dumped. Then when suflicient material has been delivered the end wall maybe closed and the loader tilted to deliverfl Under other circumstances it may better'suit to have'the rear end of the loader closed while being filled, in which event-the end ,wall may be raised and'secured in closing position.

What I claim is 1. A tilting loader having an open delivery end portion, a bottom: adapted to rest upon a support, permanent sidewalls bounding the said delivery end portion and the bottom of the loader, and a hinged wall .for the outer end of the loader adapted to be moved into substantially th l f the bottom, wherebythe loader is open at both ends, or to, be turned up into- "engagement with-the ends of-the sides to forma closing wall for the outer end of the loader.

2. A tilting loader having an oen delivery end and an open outer sad, at a portion 05 than is adapted to rest upon Go pies of thisipatent may be obtained for a support, permanent side wallsl'a pivoted end wall connected at its lower edge with the outer end of the bottom, and side pieces carried by theendewalls, these parts being arranged as described whereby when the end wall is let down the loader is open from end to end and the sidegpieces carried by the hinged end wall formpractical continuations of the side walls "of the loader, and

when said end wall is turned up it closes the outer end of the loader.

A pivoted tilting loader having an a open spout section to which is secured the vpivotaboutwhich the loader turns, an outer portion open at its end and having a bot tom adapted torest upon a support there being permanent sidewalls bounding both said sectionsj oftheloader and terminating on lines which are substantially perpendicular to the plane of the resting portion of the bottom, andan end wall hinged to" loader.
